Notes
In September 1986, our friends Erich Haugg, Ewald Heger and Helmut Alber went on an adventurous trip to Bolivia, from which they brought many interesting cactus and Tillandsia home. I will introduce one of these new Tillandsias, that they found on this trip.
T. gerdae was named after Gerda Haugg, the wife of the discoverer, who is our membership secretary. She is a good Tillandsia grower with a collection worth seeing in Altmuhldorf.

Differs from T. gerdae in
Plant long caulescent, the leaves not dense, partly very lax with very large internodes on the stem.
Leaves a little stiff, narrower & longer, stronger lepidote and the edges with large asymmetric trichomes, the blades bent under.
